Glacial budget definition
WebGlacial movement is the way in which a glacier stays in motion (internal deformation, basal slippage). This movement depends largely on the type of glacier (warm, cold, or polythermal-based). Types of glaciers WebThey form when tension is created as a result of the glacier moving over irregular terrain. Relate the glacial budget to the two zones of a glacier. The glacial budget is the balance or lack of balance between the gain of snow in the zone of accumulation and the loss of ice in the zone of wastage.
